Giant lactating adenoma.

Autops Case Rep 2021 Apr 15;11:e2021252. Epub 2021 Apr 15.

Universidade Federal do Espírito Santo, Medical School, Department of Pathology, Vitória, ES, Brasil.

Lactating adenoma is a rare benign breast lesion that most often presents as a small (up to 3 cm), solid, well-circumscribed, solitary, painless, mobile, lobulated mass. The highest incidence occurs in primiparous women (20 to 40 years old) during the third trimester of pregnancy. However, in the rare case presented herein, in addition to its giant size (more than 10 centimeters on palpation), this lactating adenoma is distinctive due to the presence of multiple nodules, poorly defined ultrasonographic margins, worrisome radiologic features, growth since early pregnancy, presence of infarction and association with chronic mastitis.

Primary breast tuberculosis: imaging findings of a rare disease.

Insights Imaging 2021 Feb 15;12(1):19. Epub 2021 Feb 15.

Department of Radiology, Faculty of Medicine, Istanbul University, Istanbul, Turkey.

Breast tuberculosis is a rare form of extrapulmonary tuberculosis which tends to affect females of reproductive age, and is much rarer in males, postmenopausal women, and pre-pubescent girls. It is difficult to diagnose because it can mimic benign conditions such as a fibroadenoma, as well as malignant diseases like a carcinoma. It is also particularly difficult to distinguish breast tuberculosis from granulomatous mastitis, so other possible diagnoses should be ruled out first. Read More
